Management module removal and replacement
This section describes how to remove and replace a management module (MM). Each Brocade VDX
8770-8 chassis can have one or two management modules. They reside in slots M1 and M2. There
must be at least one MM installed for the chassis to operate.
Time and items required
The replacement procedure for the MM takes approximately 30 minutes. The following items are
required for the MM replacement:
• ESD grounding strap
• Workstation computer
• Serial cable
• IP address of an FTP server for backing up the Brocade VDX 8770-8 configuration
• #2 Phillips screwdriver
• Replacement management module
Faulty management module indicators
Confirm that you need to replace the management module. The following events might indicate
that a management module is faulty:
• The status LED on the management module is lit steady amber, or the power LED is not lit.
• The management module does not respond to Telnet commands, or the serial console is not
available.
• The show mm command does not show that the management module is enabled.
• Additional information from the show mm command indicates a problem.
• The clock is inaccurate, or the management module does not boot up or shut down normally.
For more information about error messages, refer to the Network OS Message Reference.
